Inspection Characteristic

In this section you maintain the master records for inspection characteristics.

Master inspection characteristics are defined at the plant level. They are used as a copy model or referenced when you create inspection plans. If a master inspection plan is referenced, the inspection plan references the current version of the master inspection characteristic. You can also reference master inspection characteristics from within the material specifications.
Master inspection characteristics, in turn, can reference inspection methods and catalogs.



1. Define the structure of the master records.
a) Define number ranges .
Decide whether the number assignment will made internally or externally. SAP recommends that you use the automatic internal assignment of non-mnemonic numbers; for field for mnemonic names, you can use the master record sort field.
Make sure the number ranges that have been set in the standard system will be sufficient.
b) Specify version creation.
Determine whether you want to document the changes to the master records in the system with the help of new versions and if so, specify when these changes are to be documented. In the menu option 'Settings at plant level,' set the appropriate control indicators.
c) Define the nomenclature.
If the nomencalture is clearly defined, you can find the master records more easily. For this reason, define the contents of the following master record fields:
- external number (if applicable)
- short text
- sort field
You can use the short text to search in the master record lists and the sort field to search by matchcode.
d) Adapt matchcodes.
Make sure that the matchcodes contained in the standard system will be sufficient. If necessary, define your own matchcodes.
e) Define the classification.
With the help of the classification system, you can:
- organize master records according to classes
- conduct structured searches for master records
- distinguish master records on the basis of class characteristics
With the help of class characteristics, you can determine where the master inspection characteristics are used; you can thereby evaluate the inspection results independently of plans or materials on the basis of the master inspection characteristics.
If you want to use classification system, you must define:
- a class hierarchy for categorizing the master records
- key words for master record searches
- class characteristics for the description of the master records
f) Define the contents of the master inspection characteristics.
Specify which fields should be used in the inspection characteristic master record and how they should be used. Make sure the long texts are organized uniformly.
2. Define the check tables.
a) Define the inspector qualifications.
b) Define the characteristic weights .
c) Define the control indicators for the characteristic attributes.
d) Define the tolerance keys for quantitative characteristics.
3. Make preparations for the transfer of data.
If you want to transfer part or all of the master records for inspection characteristics from other systems, you must clarify the requirements for these technical processes.
4. Create the inspection characteristic master records.
Create the general-purpose inspection characteristic master records before you create the inspection plans.
If the inspection characteristics are to be used for the inspection specifications (currently only possible for quantitative characteristics), you must also maintain general characteristics and batch classes. Refer to the introductory chapter of the book titled " Quality planning " for additional information.
